Post-traumatic stress disorder (PTSD) is a type of anxiety disorder that can develop after experiencing a very traumatic or life-threatening event. Feeling physically threatened or witnessing violence, even if you were not physically injured, can lead to PTSD. Post-traumatic stress disorder can be terrifying and even disabling for some people. It can cause flashbacks, sleep problems and nightmares, feelings of isolation, guilt, paranoia, and sometimes panic attacks. Examples of traumatic events that can lead to PTSD include:
War combat.
Terrorist attacks.
Violent crimes, such as a ****, domestic abuse, or physical assault.
A serious accident or injury.
A natural disaster, such as a fire, tornado, flood, or earthquake.
Ongoing physical or sexual abuse.
